It's a certain number of steps that determine and egg, so just walk or run alot.

A female growlithe/arcanine and anything else in growlithes/arcanines breeding group or a ditto and any growlithe/arcanine.
Yes. It is against the law you will be arrested and prosescuted. Maximum sentence life in jail. So dont do it if you do its sooo badass.

No.
Depends on what Pokemon you want.
You cannot get Legendary Pokémon Eggs in Pokémon LeafGreen due to Legendary Pokémon being incapable of breeding.
Trade Colloseum or evolve Houndour (to get by trading Houndoom from Colloseum and breeding).

All Pokemon evolve differently. Here's a breeding key (scroll down when you get there) http://www.serebii.net/pokedex-rs/
It's by steps. In Leaf Green and all in Pokemon games where breeding is possible, the daycare has a chance of finding an egg every 256 steps. Neither game time nor real time affects the time it takes the day care couple to find an egg.
Pokemon LeafGreen does not have a time system. This makes it impossible to do evolutions that involve time such as evolving Eevee into Espeon or Umbreon.
any time [if you're talking about leafgreen].
Time is not kept in leafgreen meaning there is no day or night.
around 5, because the dog will get old, and the hips on the dog aren't that good for breeding, and mounting! you should wait before 1-4 for breeding!
Dratini can't learn Extremespeed in LeafGreen, but can learn it through breeding and as a prize in Crystal, HeartGold and SoulSilver. After answering all the Dragon Master's questions correctly in the Dragon Shrine, a Dratini with Extremespeed will be given as a prize.
